HEATING-STOVE.

Specification of Letters Patent.

Applicationfiled January 28, 1919. Serial No. 273,606.

To all whom it may concern:

Be it known that I, ELMER O. PARK, a citizen of the United States, residin at Greenview, in the county of Menard, tate of Illinois, have invented certainnew and useful Improvements in Heating-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in heating stoves.

One object of the present invention is to provide a novel and improved stove of this character wherein the heat radiation is greatly increased with the normal expenditure of fuel.

Another object is to provide a novel and improved structure of this character wherein the circulation of the products of combustion between the inner and outer drums of the stove results in greater heating efli ciency.

A further object is to provide a novel and improved device of this character wherein the inner drum is of greater diameter than usual and thus disposed in closer proximity to the outer drum with the result that the intensity of the heat between the outer drum and inner drum is raised and maintained at a higher temperature than in previous devices heretofore.

A still further object is to provide a novel and improved stove of this type wherein the gas from the fuel will be completely consumed, thus preventing escape thereof when the drafts are turned off or partly 01f.

Other objectsand advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In" the drawing:

Figure 1 is a vertical sectional view through a stove made in accordance with my invention.

Fig. 2 is a vertical sectional View taken in a plane at right angles to that of Fig. 1.

Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 1.

Referring particularly to the accompanying drawing, 10 represents the casing of the stove, with the fire-pot 11 in the lower portion thereof. Within the casing 10, and spaced a short distance from the wall of the casing, is the inner drum 12. Ordinarily this inner drum is spaced a considerable distance from the outer casing of the stove thereby producing a large space surrounding the inner drum in which loss of heat results. The present spacing of this inner drum is for a special and novel purpose, as well as an eflicient and beneficial result. The lower portion of inner drum 12 is formed with a plurality of small openings 13 in which the gas from the coal burns, and is prevented from escaping through the flue. Thus the combustion of the coal is complete and the increase of heat from the same amount of coal assured.

Extending transversely through the up per portion of the inner drum 12, and hav ing its ends disposed through the opposite sides of the casing 10, is a pipe 14. The ends of the pipe are provided with regulating damper slides 15, to control the inflow of air to the pipe. In the center of the pipe there is formed a stop wall 16, and at one side of this wall, and in the lower side of the pipe, there is formed an opening 17. Pivotally suspended on the pipe 14, and directly below the opening 17, is a pipe 18 which depends centrally within the inner drum 12 and has its lower end disposed a short distance above the lower end of the inner drum 12. At the other side of the wall 16 the pipe is formed with an elongated opening 19 in its lower side. The pipe 18, being pivotally suspended, will readily move or swing, when struck by fuel which may be violently thrown into the fire-pot, thus preventing breakage of the pipe. The outer casing 10 is provided with the usual smoke flue 20 in the side of the top thereof.

In the operation of the stove,the products of combustion pass upwardly from the fire around the inner drum 12 and out the flue 20. Gas from the coal will issue through the small openings 13 and be burned, thus increasing the heat between the inner drum and casing. -Air will enter the pipe 14 from both sides of the stove and be discharged downwardly onto the fire and upwardly between the casing 10 and the inner drum 12, thereby producing a circulation of air through the stove. Attention is called to the fact that one end of the pipe 14 is located directly beneath or very close Patented May 4, 192 0. I

to the flue 20, whereby the air which passes through said pipe will be heated to a very high temperature.

What is claimed is:

A heating stove including an outer casing and an inner drum the latter being spaced from the outer casing and having its upper end closed and its lower end open and disposed above the fire-pot, a transverse air conveying pipe disposed through the upper portions of the drum and casing and having controlling devices in the ends thereof, the intermediate portion of the pipe having a stop wall, the lower portion of the pipe at one side of said wall being formed with an elongated opening for discharging air downwardly into the inner drum, the lower portion of the pipe at the other side of the wall being formed with a smaller opening, and a depending movable pipe mounted on the pipe below the smaller opening for discharging air directly onto the fire.

In testimony whereof, I aflix my signature, in the presence of two witnesses.
